[TIMOB-20399] If you pass the device_token to users/logout, then the device is still subscribed for push notification

*Details:* If you pass the device_token to users/logout, then the device is still subscribed for push notification. *Notes:* * This is *not a regression* since this occurs with current production dashboard. * CLOUDSRV tickets are not public, so this ticket will represent CLOUDSRV-4796. *Steps to reproduce:*

Run the attached shell script:

** The script is already configured with a *preprod* Titanium app that has push notification configured. ** The script will log in a user, subscribe a device token, and log out with the device_token parameter.

Check https://360-preprod.cloud.appctest.com/#/api/data/e45cf3b8-40cb-4799-acdd-c681cbeeaf0a/push/devices

*Actual:* The device is still subscribed for push notifications; see attachment. *Expected:* The device should be unsubscribed for push notifications if the device token was passed to the logout method.
